This invention relates to the solution of the problem of substituting tiles for wood in the construction of greenhouse benches. Tiles have been used for benches for'twenty five years, but the trade has not adoptedthis form of construction, despite the obvious advantages of tile construction as compared with wood.

The side and end pieces of tile must be as strong as the floor lmembers and these side and end pieces must be securely locked to the adjacent floor members.

The specific object of this invention is to devise a method of making the side rail and its adjacent iioor member, whereby a single die will simultaneously produce a section of side rail and its corresponding floor member. flhese 'dies are the outlets from the extruding barrel from which the clay is forced to form the tilefsections.`

I have discovered that I can so score a tile section that when the hollow, rectangular tile is split the two halves are dissimilar; one being the side rail and the other the adjacent iioor member, with which it is locked by cement to form a very strong side and end rail construction.

Another object of this invention is to somake the ordinary floor tile that they can be assembled either to provide openings in the iioor for drainage, or to fit snugly together so that there is practically no drainage opening.

In the figures:-

is the eXtruding barrel (Figs. 2 and 3); 21 is the die or orifice bolted to the end of thebarrel; 22 and 23 are the cores mounted on the cross bar 24, which bar is anchored to the die 21 by means of the studs 27 represents the clay in the barrel 20.

The core 22 is shown mounted on the stud 50 projecting from the bar 24. Clearance between the stud and the corresponding hole in 22 permits the core2g2 to be adjusted slightly to vary the width of the sid-e ribs of the tile; set screws 55, 56 are used `to lock this adjustment in Vone plane and set screws 57 and 58 are used to lock this adjustment in the other plane.

The cross bar 24 is shown stream lined, (see Fig. 3), and the die 21 is iiared so as to lead the clay into the outlets between 2l and the cores 22, 23. The sides of the cores are also iiared forthe same reason.l

,The finished (unburnt) tile 28 is carried on rollers 36 supported by rails 37 and is scored by the knives 29, 30, 31, 32, 33, 34. These knives may be adjusted by their lock screws. This arrangement of cores and knives produces the tiles shown in Figs. 4 and 6.

By moving the knives 33, 34 to the lower position, shown in broken lines in Fig. 1, the tile shown in Fig. 5 is produced.

By. displacing the core 22, out of center, the right hand rib of Fig. 6 is thicker than the left hand rib, so that the tile will be distorted slightly after drying.

Ii one core is substituted for the two cores, then a tile as shown in Fig. 'l is produced.

After the tiles are baked they are easily split along the lines scored in them by the knives, or

the tiles can be split after drying and before burning.

In Fig. 8 the bench is shown supported by wooden 2" X 4"-40, 41, 42, 43, 44. These 2 x 4" are protected by a piece of tar paper 45. Resting on these 2l X 4" are the tiles corresponding to those shown in Fig. 4. The side rail construction shown utilizes the two sections produced by Fig. 5; the long leg 46 of the F being laid on the los long projection 47 of the E. The end construction j is here shown formed by notching the tiles 48 as shown at 49 to nt over the projection 47 of the side rail.

In Fig. 9 the side rail construction is adopted for the end rail construction. This necessitates an extra 2" x 4, as 40 and 41 are brought closer together.

In all cases, cement is poured into the joint, as shown in Fig. 12, between the long leg 46 of the F section and the long projection 47 of the E side rail section. I l N The gap shown in Fig. 12 between 46 and the rail is the clearance necessary to compensate for variations in width of the tiles and also to provide for odd Widths; the tiles being made six inches wide will nt easily into benbhes that' are an even number of feet wide.

In Fig. 1o the tiles formed assnown in nig."

7 are utilized, together with, the tar paper pro'- tection 45 for the 2 x 4".

Fig. 11 shows a plan view of the oor produced by the tile shown in Fig. 6. v

V.As these tiles all have a slight curvature, due to the fact that one outside rib is thicker than the other, it is possible to assemble them as shown, to give drainageY openings; and of course it is equally possible to assembleA themso that they fit snugly with each other. Y, Some beds require more drainage 'than others, so that this gives'the nurseryman asimple means of changing the nature ofthe liioor to suit the particular use to which the bench will be put. For example, pot benches areconstructed with snugly tting tiles to retain the sand, etc., spread on the iloor of the bench. Cut newer beds require adequate drainage.

By increasing the eccentricity of the core 22 the amount of curvature of the tile is increased.

In Fig.` l2 the side rail `5l is higher than the oor section 52 is wide. The width of the floor section is preferably six inches' and the beds are usually three feet, three feet six inches to six feet. The side rails should be six inches for cut flower benches, measuring from the inside; which meansfsevenand` three eighths inches -for' the outside. Hence, the'side rails are made in fpairs in a special extruding die, as shown in Fig. 1'4. Pot benches require the construction shown in Figs. 8, 9 and 10, forrwhich the six' inch side rail is ideal; and one die can produce simultaneously side rails and the floor pieces that engage therewith c In order to tie adjacent members of the rail together, a piece of wire 60 is threaded through a hole drilled in the toe of each side rail, the copper wire then passes around the 2" x 4 and is tied.

What I claim isz- 1. Side rail and floor construction for a greenhouse bench, comprising a U shaped tile forming the side rail and having one leg of the U longer than the other, an L shaped tile forming the side oor piece,'the long leg of the L lying on top of the long leg of the U, the short leg of the L being as high as the long leg of the U is thick.

2. Side rail and floor construction for a greenhouse bench, comprising an E shaped tile forming the side rail and having the lower projection of the E longer than the others, an F shaped tile forming theside iioor piece, the long leg of the F lying on top of the long projection of the E, which is as thick as the short leg of the F is high.

3. A greenhouse'bench floor, comprising'a plurality of tiles with curved sides assembled together so as to provide drainage `openings between adjacent tiles.

4. A 'greenhouse tile bench having a ribbed tile side rail interlocked ,with ribbed floor tiles, so that the base of the side rail is flush with the bottom of the ribs of the floor tiles.

5. A greenhouse bench, comprising lateral supports, ribbed floor tiles having ribs removed adjacent to the edge of the bench, ribbed side rail tiles having a rib extending beneath the side floor tile, means forv tying the sideoor tile to the side r'ail tile land to the lateral supports.`

6. Side rail and iloor construction for a greenhouse bench, comprising a U vshaped tile forming the side rail .and having one leg of the U longer than the other, an L shaped tile forming the side oor piece, the `long leg of the L lying on top ofthe long leg of the U.

'7. Side rail and floor construction for a greenhouse bench, vcomprising an E shaped tile forming the side rail and having the lower projection of the E longer than the others, a'n F shaped tile forming the Vside oor piece, the long leg of the Flying on top of the long projection of the E.
